A Parallactic Distance of 389 +24/-21 parsecs to the Orion Nebula Cluster from Very Long Baseline Array Observations
Karin M. Sandstrom, J. E. G. Peek, Geoffrey C. Bower +2
We determine the parallax and proper motion of the flaring, non-thermal radio star GMR A, a member of the Orion Nebula Cluster, using Very Long Baseline Array observations. Based o…
SubmilliJansky Transients in Archival Radio Observations
Geoffrey C. Bower, Destry Saul, Joshua S. Bloom +4
[ABRIDGED] We report the results of a 944-epoch survey for transient sources with archival data from the Very Large Array spanning 22 years with a typical epoch separation of 7 day…
Radio Astrometric Detection and Characterization of Extra-Solar Planets: A White Paper Submitted to the NSF ExoPlanet Task Force
Geoffrey C. Bower, Alberto Bolatto, Eric Ford +2
The extraordinary astrometric accuracy of radio interferometry creates an important and unique opportunity for the discovery and characterization of exo-planets. Currently, the Ver…
How to hide large scale outflows: size constraints on the jets of Sgr A*
Sera Markoff, Geoffrey C. Bower, Heino Falcke
Despite significant strides made towards understanding accretion, outflow, and emission processes in the Galactic Center supermassive black hole Sagittarius A*, the presence of jet…
